想必大家在使用Maven从仓库下载Jar的时候都感觉速度非常慢吧。前几年国内的开源中国还提供了免费的Maven镜像，但是由于运营成本过高，此Maven仓库在运营两年后被迫关闭了。不过高兴的是，阿里云在2016年08月悄悄上线了Maven仓库，点这里：http://maven.aliyun.com。我们可以把下面的配置复制到$MAVEN_HOME/conf/setting.xml里面：

然后使用Maven编译你的代码，这时候Maven会从阿里云上面下载Jar依赖，速度明显要比默认的快多了！

其他Maven仓库

我们还可以设置以下的Maven仓库地址，如下：

<mirrors>
    <mirror>
      <id>wso2maven</id>
      <name>wso2 maven</name>
      <url>http://maven.wso2.org/nexus/content/groups/public/</url>
      <mirrorof>central</mirrorof>        
    </mirror>
</mirrors>

替换上最上面阿里云Maven仓库地址即可。以下的地址也可以使用：

http://maven.wso2.org/nexus/content/groups/public/
http://jcenter.bintray.com/
http://maven.antelink.com/content/repositories/central/
http://maven.springframework.org/release/

http://uk.maven.org/maven2/
